Caitriona Balfe, Chloë Grace Moretz, Lenny Kravitz and more stars have suffered nip slips, pasty problems and butt blunders in the name of red carpet fashion. Here’s how to make sure the same doesn’t happen to you

CAITRIONA BALFE

The Oops: Cannes first-timer Caitriona learned the hard way that the film festival's oceanside breeze can be a bit of a bummer (get it?).

The Advice: If you've got to wear a floaty mini for your Cannes photocall, you may also have to keep your hands strategically planted at your hemline. (Alternately, you can just handle it as coolly as the Outlander star did!)

CHLOË GRACE MORETZ

The Oops: The seam on the star's lilac turtleneck top came apart mid-autograph.

The Advice: If something feels too small in the dressing room, believe it. There's no way you'll be able to stand in that perfectly slouched position where it looks like it fits all night. Don't be the girl who splits during a sneeze!

LENNY KRAVITZ

The Oops: A very important seam at the crotch of his pants split right as he sank into a squat, causing a case of extreme exposure. The Advice: It’s probably too much to ask Lenny Kravitz to wear undies with his second-skin leather pants, so we’ll just recommend that anyone in this particular situation ask a tailor double-stitch reinforcement at key areas.

ELIZABETH OLSEN

The Oops: Her navy Miu Miu dress caught a gust of wind outside the line’s Paris show – and caught the star in turn by surprise. The Advice: Doing exactly what she did – wearing a pair of full-coverage undies under a lightweight skirt – means your Marilyn Monroe moment is more saucy than skanky.

CHRISSY TEIGEN

The Oops: The supermodel experienced a wardrobe malfunction “of the highest caliber” when her Solace London dress split all the way up the front. The Advice: If your clutch is too small for a sewing kit, make sure it’s big enough to serve as a modesty shield in the event your high-slit dress turns on you.

NINA AGDAL

The Oops: The Victoria’s Secret model endured “20 minutes of lunges and squats” with a split seam before someone told her. The Advice: You’ll never be sorry you kept that extra hoodie in your gym bag for moments just like these.

BEHATI PRINSLOO

The Oops: The malfunction-prone model has flashed both her tail- and headlights on the red carpet. The Advice: If your skirt’s too short for slip shorts and your dress is too sheer for pasties, you’ll need to have Adam Levine on hand to distract the photographers. (Easy enough, right?)

SOPHIE MARCEAU

The Oops: Navigating the tricky stairs in Cannes, the French actress pulled her skirt apart to aid her movement, inadvertently giving the crowd an eyeful. The Advice: Fashion tape works below the belt too. Securing a super-high seam (or a mishap-prone wrap silhouette) may be the smart solution if you’ll be doing more than sitting all day.

EVA LONGORIA

The Oops: She revealed way more than intended while leaning over to untangle the hem of her gown post-Golden Globes (and we’re not talking about her upper thigh area, which she bared on purpose).The Advice: No matter how small your chest, if you’ve picked a dress with a cutout to your navel, you’re going to want to invest in some fashion tape.

KIM KARDASHIAN

The Oops: The mom-to-be gave the paparazzi an eyeful of her most famous asset in too-sheer skirt.The Advice: Hold your clothes up to a window in bright, natural light. Can you see through them? Then undergarments are advisable.

The Oops: She had messy brown smudges on her white leather pants.The Advice: If you’re J. Lo, make sure to have a backup pair of white leather pants (a Tide pen is just not going to cut it for these babies). If you are not J. Lo, avoid white leather pants altogether.

The Oops: Julianne ripped her Temperley London gown up both legs while dancing too hard at a Golden Globes after-party.The Advice: Should you be wearing a borrowed gown worth megabucks to a reception with great music, think hard before doing your best “Gangnam Style.”

SOFIA VERGARA

The Oops: The star busted a zipper on Emmys dress. Click here for her NSFW tweet of the disaster (don’t say we didn’t warn you!). The Advice: If you’re determined to make that super-snug dress zip, opt for Spanx, avoid sitting down all night and (on the off chance your stylist isn’t waiting in the wings with a sewing kit) bring an opaque wrap so you can make your exit discreetly.

The Oops: Katherine's dress undid itself during her acceptance speech at the ShoWest awards.The Advice: Spend some time in the garment before an important event to discover any potential issues. If it rides up, dips low or is precariously fastened, you’ll find out before it’s too late.

HAYDEN PANETTIERE

The Oops: She sported a visible pasty underneath plunging (and sheer) gown. The Advice: Enlist a friend to take photos of you with a flash camera before leaving the house. What looks great in your bathroom mirror may appear very different in an iPhone pic posted to Facebook.

The Oops: The royal's pretty yellow dress fell victim to a gust of wind.The Advice: If you don’t have a royal dressmaker to weigh down any hems that might inadvertently give you the full Marilyn Monroe, make sure you opt for full-coverage boy shorts.

The Oops: Emma's dress was ’90s-chic from the front and eye-popping from the side.The Advice: Find a good tailor who can transform that beautiful but less-than-perfect-fitting piece into a couture-worthy creation.
